Barangays in west coast areas experienced low pressure to no water starting Friday, April 26, 2013 up to Saturday of April 27, 2013 as water production was reduced due to flood that was reported on Thursday evening and Friday afternoon. Dam level increased to as high as 74.92 meters with a turbidity of 1,800 ntu requiring frequent cleaning of the filters and resulting to a decrease of water level in the reservoirs. The normal turbidity is 5ntu.Residents of San Jose Gusu, Upper Cabatangan, Upper Calarian , Sinunuc, Cawit and portion of San Roque, specifically those located in highly elevated areas and farthest most point of distribution, complained of no water in their areas. ZCWD immediately dispatched water delivery tankers injecting water in distribution lines of affected areas in order to mitigate the situation. Water pressure improved on Sunday, April 28, 2013 as water level in the reservoirs started to pickup with turbidity going down to 6ntu. Earlier of April, the same problem was experienced at the west coast area due to the reported flash flood inside the watershed. ZCWD is continuously monitoring the inflow in the Tumaga River, as well as, the unpredictable weather condition affecting the city of Zamboanga. In the meantime, ZCWD GM Leonardo Rey D. Vasquez is advising all consumers/customers, especially those living in highly elevated areas, to store water for use during unscheduled water interruption.
